Power relays are a type of switch that can be used to automate electrical tasks, and the HJ4-AC-100V-R is one such relay. These relays can be used in applications that require high-power switching, and are rated for over 2 amps. This article will discuss the HJ4-AC-100V-R\'s application field and working principle.

Application Field

The HJ4-AC-100V-R is mainly used in industrial and commercial applications, such as machinery control, power control, lighting systems, motor control and HVAC systems. It can also be used for motor and machinery control, home and commercial security systems, and other automated processes. In addition, this relay can be used in applications that require a high-power switching, such as the switching of large current levels.

Working Principle

The HJ4-AC-100V-R operates on the principles of electromagnetism. When energized, an electromagnet generates an electromotive force that causes the contact points of the relay to close, allowing current to flow. When the current is turned off, the electromotive force is reversed, and the contact points open, stopping the current flow.

The HJ4-AC-100V-R is a single-throw, double-pole (STDP) power relay, meaning that it contains two sets of contact points. This ensures that the current is being properly turned off when the energizing force is reversed. Additionally, it has a high current rating, meaning that it can handle large amounts of electric power without damage.

Advantages

The HJ4-AC-100V-R has several advantages over other types of power relays. It has a high current rating, meaning that it can handle larger currents than other types of relays without damage. Additionally, it is a double-throw relay, meaning that it can simply be turned off and on with the flip of a switch, making it easier to use than other types of power relays. It is also a very reliable type of relay, as it is designed to withstand frequent switching.

Conclusion

The HJ4-AC-100V-R is a single-throw, double-pole power relay that can be used in applications that require high-power switching. It is commonly used in industrial and commercial applications, such as machinery control, power control, lighting systems, motor control and HVAC systems. The HJ4-AC-100V-R operates on the principles of electromagnetism, and has a high current rating. Additionally, it is a very reliable type of relay, as it is designed to withstand frequent switching. Overall, the HJ4-AC-100V-R is an ideal choice for applications requiring high-power switching.
